The application of PVD coating on stainless steel workpiece is mainly reflected in the improvement of product corrosion resistance, wear resistance, oxidation resistance and aesthetics.
(1) Improve corrosion resistance: PVD coating has high hardness and low coefficient of friction and other characteristics, can form a layer of protective film on the surface of the product, to protect stainless steel products from corrosion, significantly improve its corrosion resistance. For example, stainless steel PVD coated products can achieve a corrosion resistance time of 120 hours when salt spray test is conducted.
(2) Increase oxidation resistance: PVD coating can effectively prevent oxidation of stainless steel products in high temperature environments, improve its oxidation resistance.
(3) Increase wear resistance: PVD coating has good wear resistance, can effectively protect the surface of stainless steel products and extend their service life. For example, stainless steel products treated with PVD coating show excellent wear resistance and oxidation resistance during salt spray test and oxidation temperature test.
(4) Improve the surface gloss and aesthetics: after PVD coating treatment, the surface of the product will become smoother and flatter, thus improving the surface gloss of the product and making it look more beautiful.
To sum up, the application of PVD coating on stainless steel iron workpieces significantly enhances the performance and added value of the products by improving their corrosion resistance, abrasion resistance, oxidation resistance and aesthetics, so that they can maintain good performance and appearance in various environments.
